ROTARY MEASURING DEVICE.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed April 14, 190s. serial No. 426,932.

To all whom t may concern:

Be it known that I, SHoJi IRrNo, a subject of the Emperor of Japan, and a resident of Salt Lake City, in the county of Salt Lake and State of Utah, have invented a new and Improved Rotary Measuring Device, of which the following is a full, clear, and exact description.

This invention relates to measuring devices, and more particularly to devices of this class each of which has a rotatable measuring wheel, distance indicating mechanism controlled thereby, a detent for holding the wheel immovable when it is not in use, and lneans for positioning themeasuring wheel with its point of contact with the ground, at a predetermined distance from a Fixed point, so that it is possible therewith to measure accurately a distance, starting from a wall or other obstruction.

An object of this invention is to provide a simple device which has means for indicating exactly, the distances lneasured thereby, in feet or inches or other suitable units, and which can be used for lneasuring distances starting at obstructions such as walls and the like.

A further object of the invention is to provide a device of the class described having the rotatable measuring wheel provided with an edge scale, and having a pointer indicating at the scale, and further having an elongated member or rule arranged at thev extremity of the pointer and adapted to be adjusted to project beyond the periphery of the wheel so that it is possible to place the wheel witll the point of contact with the ground, at a predetermined distance from an obstruction such as a wall, the predetermined distance being the length of the member.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the views, and in which- Figure l is a side elevation of my invention; Fig. 2 is an enlarged longitudinal section on the line 2-2 of Fig. 4; Fig. 8 is an enlarged longitudinal section of a part of the device on the line 3--3 of Fig. 4; and Fig. 4 is an enlarged section on the line ll--fi of Fi l.

Before proceeding to a more detailed eX- planation of my invention, it should be clearly understood that while I have shown, for example, a measuring device for determining distances or lengths in feet and inches, it can also be easily adapted for measuring in other units, for instance in the linear units of the metric system. Preferably, the rotatable measuring memberor lll-l l f--m 'h wiee las a rac lus o 2X3'14159 inc es, so that the circumference is substantially one foot, or twelve iliches. The measuring wheel is provided at the edge with a scale graduated to, represent twelve inches, and it further controls a pointer which coperates with a dial. indicating inches from one to twelve. Additional dials are provided, which are graduated to represent tens, hundreds, and thousands of feet, and which have pointers connected by suitably proportioned gears and controlled by the measuring wheel. I provide a suitable normally operative detent for holding the wheel immovable when it is not in use.

As the wheel is of circular form it is impossible to arrange it adjacent to an olostruction such as a wall, and in a plane at right angles to the wall, with its point of contact with the ground, adjacent to the obstruction. Consequently, when a distance is measured, starting from such an obstruction, the resulting determination will be incorrect, as the measurement was not started exactly at the obstruction. To avoid this difficulty I provide an adjustable member of predetermined length, which permits the positioning of the measuring device with its point of contact with the ground at the same predetermined distance from the wall ol' other obstruction, and consequently, it is merely necessary to add to the final measurement a distance equal to the predetermined distance, to make the result correct.

Referring more particularly to the drawings, I provide a frame l0 fashioned from metal or any other suitable material and having opposite, substantially parallel sides 11 and 11d. The sides are curved or tapered toward 7the extremities, as is shown most clearly in Fig. 1, and have therebetween a Wall or partition 12 preferably .integral with the frame 10. The side 11 andthe Wall 12 have a pivot pin 13 provided with afsuitable head 1a engaging at the outside of the side 11. A rotatable measuring Wheel or member 15 is mounted upon the pin 13 and is rigid therewith.

The Wheel 15 has, at the side adjacent to the side 11 a notched .plate =or ratchet 16, .secured thereto by means of -screivs 17 or `in any .other :convenient manner. The frame 10 has a boss 18, provided with an opening in which .is .movably arranged. Aa Apin '19, ihaving a :head 2O by means of which it can be manually operated. at the inner end ofthe pin 19 is a `iler/cible strip 21, having laterally disposed toes 22 at the ends, and forinin-g a idetent to engage at the peripherally notched plate 16. ,Studs 23 at the inside ofthe side 11 lof the frame, .engage the strip 21 and hold the 4toes 22 norma 2 y in engage ment at the rim of the plate 16. The strip 21 is flexible, and by pressing upon `the pin 19 it 4can be so bent that the toes 422 are lifted from vengagement `with the plate to permit the measuring Wheel to rotate freely.

The Wheel 15 is preferably provided With a groove 211 in the rim thereof, in Which Eis located a tire 25 of rubber or the like to prevent the slippingof the Wheel. The tire projects very slightly beyond the Wheel and thus does not materially increase the diameter of the same. The Wheel iis provided at the side, near the edge, with a scale 26 graduated in inches or other units.

rhe pin 13 has a constrictedextension 27 which projects through a suitable opening of :the other side 11a and carries .a pointer 28 `arranged ito cooperate With a dial 30 mounted upon the side 11a. The .dial has a rim 31 ,and a covering glass 32, and is graduated in units similar to those of the scale upon the measuring Wheel. As the latter is rigid with the pin 13 the `pointer 28 Will be actuated to correspond to the movements of the Wheel. Further dials 33 are formed upon the side 11a and have rims 31 and covering glasses Fivot pins 36 are carried between the Wall 12 and the side 11a., and have pointers 37 :arranged to cooperate with the dials 33. The pins 36 have rigid therewith, gear Wheels and pinions 38 and 3.9, which are in mesh with each other, as is shown most clearly in F ig. V2v, and which bear acertain relation according to the units of the scales. The first of the gear Wheels 38 is controlled by the pin 13 through finteii'mediate pinions l0 and Ll1. rllhe arrangement is such that each time the `measuring Wheel makes a complete `renfolution the pointer 28 makes a complete revolution and the ,pointer 37, cooperating with .the first dial imoves thfrough .one unit of the scale upon the rst dial 33. The second dial 33 is moved one .unit after the irst pointer 37 has made a complete revolution of the first dial .33. The arrangement is the usual one `near the extremity thereof, and ilmS :a ij'ont 4.5 so .that `it can be varied and adjusted itc lie alined with .the gpointer. Tfhe member j44 is of predetermined length and ,can be `adkjusted .to project beyond the peripheryiof .ehe

measuring wheel, -as is shown unost 1cleanly in 2, to permit #che positioning of the measuring Wheel with its point fof contact with the ground, at :the predetermined {distance frein the obstruction, suoli 1as :a wall.

Having thus l.described my invention, I claim vas new, and desire Yto secure by Letters Patenti* l.
